most marijuana strains are very forgiving..
What you want to do is keep soil temperatures ideal (not too cold)
not water too often or over water
not start feeding too early
with those three things, most strains are forgiving.. Most "hardy" strains are hardy under certain conditions.. For example, i grew frost dragons in some extremely cold root zone temperatures and they flourished really well. One of the hardier strains i've grown in that environment.. I've grown akr in 100-107 degree temps with good results.. Very forgiving in the heat.
I'd put more faith in my ability to grow and continue to learn and don't look for a hardy strain but look to hone your skills and follow all the advice given..
